Thick Scum Build Up Around Toilet

Hi Bec,
If there is a drain hole in the floor maybe you could get out the big guns & gerni (high pressure cleaning) the heck out of it. I'm surprised that the pool acid didn't put a dint in it! Or spray (experiment with different cleaners) & scrap with a paint scrapper. Good luck.

Is there a difference between white vinegar and cider vinegar, that the white would work and not the other? Just wondered because I was given 4 gallon jars of cider vinegar.

Use White vinegar it is really eating up scum. Apply and wait for 5-10 minutes and then scrub with hard sponge.

Use White Vinegar.
It kills scumb, mold & lime and all dirt. You can actually wash mildew off walls using vinegar & a mop.
Vinegar is cheap, Easy to use and the vinegar smell goes away in a day or less.

I think you would be ahead to call this toilet a loss, and just replace it.

Try spraying it with white vinegar, let it set a few minutes and then scrub.

Try soaking paper towels in white vinegar and leaving them on the affected areas. I've been amazed at what white vinegar can clean!

Try Mean Green,It works great for me.I have found it at the Dollar General,Family Dollar,and Walmart Stores.People even use it to detail their vehicle.I hope this will help you out ,Bonnie from Kentucky

I have found that the cleaning product Greased Lightening can take up ANYTHING! Good Luck.
